Dear friends,
Lats night I sat down to finish some business with Sh2-101 in Cygnus and which is perhaps more commonly known as the Tulip Nebula.
I imaged this gem two years ago but never circulated the result due to the noise result which was produced by my ST-2000XM (at least when looking at the hires version). Last night was prime for a repeat visit due to the fact that I had very good transparency as well as very good seeing.
My only apprehension was the fact that there are two bright stars within the central portion of the field of view and which somehow ties my hands in relation to how deep I can go with my (blooming) ST-10XME. Unfortunately I had to restrict me integrations to six minutes and in contrast to my desired 10- or 15-minute subs.
For a result based on four hours total time, I kindly refer you to
www.perseus.gr/Astro-DSO-Nebulae-Sh2-101.htm
for the RRGB result (120:60:60:60) and please make sure you click on the hyperlinked image for a larger version of the same. I hope to revisit this target with a better ABG camera and deeper integrations at some point in the future.
Clear skies.
Anthony.
